Nana56. Hi sorry to hear your husband has been diagnosed with BVVP, it’s very distressing when an attack comes on,
My husband had this a few years ago , we went to various specialists after tablets for dizziness did not help him
A consultant at Aintree Neuro dept, Liverpool did the Epley manouvre on him which done properly dislodges any crystals in the ear that are in the wrong place, and that’s what causes the dizziness,
The consultant showed me how to how to do these movements which involves turning the head different ways,
The next time my husband had an attack of BVVP. I was able to do these and he hasn’t had an attack since, now ,whether it was the manouvres or he was just getting better I don’t know,
The attacks lasted on and off for a couple of years until we sought help,
I hope your husband gets some help and certainly ask about the Epley manouvre when you see your GP. Good Luck
